Anxiety isn’t a single condition. Several distinct disorders share anxiety as a core feature but differ in what they focus on — broad everyday worry, sudden panic, fear of judgment, or fear of specific situations. Knowing which type fits your experience helps point you toward the treatment most likely to work, and it’s common to have more than one at once.
Key facts
- Anxiety disorders are the most common group of mental health conditions; NIMH estimates about 19% of U.S. adults have one in a given year.
- An estimated 301 million people worldwide were living with an anxiety disorder in 2019 (WHO).
- The recognized types share anxiety but differ in focus and triggers (NAMI).
- People often experience more than one type at the same time, and all are treatable (NIMH).
Generalized anxiety disorder (GAD)
Persistent, excessive worry about many everyday things — health, money, work, family — more days than not, often for six months or longer. The worry feels hard to control and is usually accompanied by physical symptoms like restlessness, muscle tension, and trouble sleeping.
Panic disorder
Recurring, unexpected panic attacks — sudden surges of intense fear that peak within minutes — plus ongoing worry about having more. Read more about panic disorder, and see how a single anxiety vs. a panic attack differs.
Social anxiety disorder
Intense, persistent fear of being judged, embarrassed, or scrutinized in social or performance situations — strong enough to interfere with daily life. Learn more about social anxiety disorder.
Specific phobias
Strong, persistent fear of a particular object or situation — such as heights, flying, needles, or animals — that is out of proportion to the actual danger and leads to avoidance.
Agoraphobia
Fear of situations where escape might be difficult or help unavailable, such as crowds, public transit, or being far from home — sometimes leading a person to avoid leaving home. See agoraphobia.
Other related conditions
A few conditions involve anxiety but center on a specific theme:
- Separation anxiety disorder — excessive fear of being apart from people you’re attached to.
- Health anxiety (illness anxiety disorder) — persistent worry about having a serious illness.
OCD and PTSD were once grouped with anxiety disorders and remain closely related, but are now classified separately — see anxiety vs. OCD and anxiety vs. PTSD.
From our clinical review. The labels matter less than people fear. What helps is naming the pattern — “this is panic,” “this is social anxiety” — because each one has a treatment with a strong track record. And if you have two at once, that’s normal, and we can treat them together.
Recognizing your type of anxiety is a useful start. See anxiety treatment options — or take a private, two-minute anxiety self-check.
Frequently asked questions

What is the most common anxiety disorder?
Specific phobias and generalized anxiety disorder are among the most common. All types are treatable, and many people experience more than one at the same time.
